    These are the only 3 known prime numbers whose digits are in ascending order, beginning with 1 and returning from 9 to 1 or 0 where necessary.pic.twitter.com/x5drH0hyFt

        The second one isn't beautiful because it returns to 0 and 1 in two different cycles. There is no prime that returns to 0 only.

        But I really like the fact that I've now memorized a 28-digit prime number.

        Totally random observation/thinking: if you remove 8 from the first it's still prime (123456791 is prime) if you insert three extra 8s in the third it's prime too (1234567889123456788912345678891 is prime)pic.twitter.com/35T9sMGwdH

        In West Chapel, Maine, Mrs. Eliza Coote-Pinkey use this fact to arrange her used clothing store. Unfortunately, people confused the numbers on the shelves for sizes rather than the number of buttons or hooks on particular garments. They became frustrated and left promptly.
